well i found here that what i said earlier about mountain dew is not true, and i'm still looking into other soda to see if that's true, because the internet has contrasting views on everything.
If you were tight underpants, or those like bonds, the Y fronts, it is proven it does lower sperm count a lot. Since sperm needs a low temeperature in order to survive so when you wear tight underpants, it squeezes the um 'bag' closer to the body, raising the temeperature therefore killing and lowering sperm count.
by the way, here is a great urban legend/myth site to see if the they're true or not. my mom found it a few months ago and i came across it while searching for stuff about this. it doesn't have anything about soda in general lowering sperm count, but it again says that mountain dew does not.
By real sugar do you mean not Diet/Sugar Free? If so, then yes, real sugar tastes far better. I drink a lot of Irn Bru - dunno if they sell it in America.
no, we mean sugar rather than high fructose corn syrup.
I really don't care. Most people really won't either, considering how people don't care how much sperm you have.
